APPARATUS FOR LAYING CONCRETE ROAD-BEDS.

Specification of Letters Patent.

Patented June 29, 1909.

To all whom it may concern:

Be it known that I, FRANK M. TALBOT, of Glenridge, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Laying Concrete Road-Beds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide improved means for laying road beds of concrete, having reference to what are commonly termed tracks, that is the ballast and ties which form the base or foundation for railroad rails.

As well understood in the art, it is necessary to adjust and secure the ties or sleepers at the proper height and disposition and support them while the ballast is being laid. The supporting devices may form a permanent part of the way or track when the ballast is of road metal, that is gravel, broken stone and slag, or they may be only temporarily used as when concrete constitutes the road bed and ballast. In either event it is of course essential that the structure be trued with nicety. When laying concrete tracks it is customary to support the ties and guard rails by means of underpinning and liners, adjust them carefully and then pour in the concrete. It is customary to lay only a few feet of track at a time by this method.

By my invention the adjustment of the ties and guard rails is materially simplified and the extent of track which may be laid after one adjustment is increased.

In the accompanying drawing I have shown in Figure 1 an apparatus appropriate to carrying out the invention, the view being a transverse section of a tunnel through which a railroad line is being laid. Fig. 2 is a artial perspective.

have shown a frame 1 movable longitu dinally upon wheels 2. In Fig. 1 the wheels are movable on rails 3 supported by ledges 4 at the sides, although the precise manner of movably supporting the frame is of course not important. It should of course be supported independently of the newly laid ballast, however. The frame is shown with depending side pieces 5 suitably braced and supporting a flooring 6. This floor carries a series of adjustable hangers '7 vertically disposed and threaded at their upper ends to I receive nuts 8 bearing against blocks 0 throughw'hich and the floor the hangers extend, their lower extremities being T-shaped or formed with lateral portions '10.

12 designates the ties or sleepers and 13 the guard rails mounted thereon. 1-1- indicates the rails. The rails, however, are not laid until after the road bed is completed and they, as well as the particular form of ties, do not enter into my invention. I have shown, however, ties extending only partially across the way, that is each tie is independent of the transversely opposite tie, this being a form well adapted to concrete tracks.

I have shown beams 15 resting upon each of the two series of ties, each beam extending longitudinally of the track and transversel r of its respective ties and secured to the latter as by lag screws. These beams constitute part of the temporary support. The hangers '7 are designed to engage these beams 15 and the guard rails 13, as shown in Fig. 1, by turning the hangers axially until their lateral portions are beneath the beams and guard rails.

16 designates a concrete car movable on rails 17 mounted upon the floor (5.

In practice I make the frame about 150 feet long, equip it with the necessary number of hangers and secure the beams upon the ties. The guard rails 13 are of course a permanent part of the structure. The hangers are turned to bring their laterals 10 beneath transit then determines the height at which the ties should be held and the hangers are adjusted accordingly by applying wrenches to the bolts 8, the ties, beams and guard rails moving with the hangers. This is readily accomplished. The concrete is then dumped from cars 16 and spread out by attendants until it fills all the space beneath and between the ties and is flush with the latter as indicated at 18. When the filling of concrete has been laid throughout the length of the frame, bolts 8 are loosened and the hangers turned axially to remove their lateral portions 10 from the beams and guard rails and they are lifted from the filling. The entire frame is then free and may be me ed along the rails 3, the beams 15 removed and the described operation repeated.

W'hile I have shown the apparatus as adapted to laying a single track, yet it is obvious that it is only necessary to widen the frame 1 and duplicate the supporting devices the beams 15 and the guard rails. The

in order to lay a double track in one operation.

I claim as my invention 1. Means for laying tracks or road beds having ties or sleepers, comprising a supporting structure extending over the space the track is to occupy and itself supported on opposite sides of said space, and adjustable devices depending from said structure and adapted to engage and hold said ties while the filling of said track is being laid.

2. Means for laying tracks or road beds having ties or slee ers, comprising a supporting structure bridging over the space the track is to occupy, means for movably mounting said structure on opposite sides of the road bed, adjustable hangers depending from said structure and adapted to engage and form temporary supports for said ties, and means for transporting concrete or other lilling over said structure and discharging it therefrom into the space beneath and be.- tween said ties to form the permanent support for said ties.

3. In an apparatus adapted to form a temporary support for railroad ties while the filling to constitute the road bed or ballast is being applied, the combination with the movable supporting structure, of adjustable hangers depending therefrom, beams temporarily secured to said ties, means for detachably securing said hangers to said beams, and means for vertically adjustmg said hangers.

a. In an apparatus adapted to form a temporary support for railroad ties while the 'lilling to constitute the road bed or ballast is being applied, the combination with tne ties having guard rails thereon and beams secured thereto, of a supporting structure, and adjustable hangers depending therefrom and having lateral portions at their lower extremities adapted to engage said beams and said guard rails.

5. In an apparatus adapted to form a te1nnorary support for railroad ties while the fillling to constitute the road bed or ballast is being applied, the combination with the ties having guard rails thereon and beams secured thereto, of a supporting structure comprising a frame having rollers, tracks for said rollers at either side of said road bed, said frame having a central flooring directly over said road bed, adjustable l'rangers depending from said flooring and having lateral portions at their lower extremities adapted to engage said beams and said guard rails, and means for transporting concrete over said flooring and discharging it therefrom.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
